Step 1: 

Locate the thermostat housing & unplug the ECT/fan switch plug. It is usually located beneath the intake arm and distributor. Unbolt the 10mm bolt holding the ground terminal.

Step 2: 

Remove the upper radiator hose from the thermostat housing. I recommend placing a towel underneath as a small amount of coolant will spill out. 

Step 3: 

Remove the 2 x 10mm bolts and remove the thermostat cover. I recommend placing a towel underneath as a small amount of coolant  will spill out.

Step 4: 

Remove the old thermostat. Prepare the new thermostat with its proper rubber gasket. Here you can see the OEM thermostat on the left and a AutoZone generic brand on the right.

REMEMBER:

Install with pin up. 

Step 4: 

Clean the surface area & scuff off the leftover liquid gasket.

Step 5: 

Place the new thermostat (pin up) inside the thermostat housing.

Step 6: 

As a precaution, I recommend applying liquid gasket maker on the outer thermostat housing for a better seal to avoid leaking. Reinstall the two 10mm bolts with 12nm/8.7lb. Plug the ECT/fan switch & mount ground terminal.
